Panel A shows the test-retest reliability of the online measure. Panel B presents the test-retest reliability of the offline-online composite score. Note that both coefficients might be over-estimated due to two observations (top right corner in both graphs). The test-retest coefficients, however, remained high even when removing these data points: r = 0.45, and r = 0.72, for online and composite scores, respectively.
